Celestron 120mm f/8.33 Omni XLT Refractor OTA

Attach this Celestron Refractor OTA to your choice of alt-azimuth or equatorial mount and you’ll have a superb telescope for exploring the Solar System or delving into deep space. With almost 5” of aperture that gathers almost 300X that of the human eye, you’ll be able to see faint details with the Celestron Omni XLT 120. Check out the Andromeda Galaxy, the wispy structure of the Orion Nebula, or the Great Red Spot on Jupiter! The Moon will simply blow you away, and the rings of Saturn will be a sight you’ll never forget!

If you choose to mount this Celestron Refractor OTA on a simple alt-azimuth mount, and add an erect-image diagonal, you’ll have a very powerful terrestrial scope that can also be used for nighttime viewing. For those with a view, the Celestron Omni XLT 120 will provide stunning images of wildlife, ships at sea, or other interesting daytime subjects. If you add a safe, properly sized solar filter (contact us for options) to the front of your scope, you can observe sunspots and safely watch solar eclipses! This telescope is truly a flexible instrument.

The Celestron Omni XLT 120 Refractor OTA sports quality optics that are fully coated with Celestron's famous StarLight XLT coatings. These optical coatings are used on Celestron's observatory-grade telescopes as well and will help ensure crisp views and maximum light transmission on your Omni 120.

The smooth, easily adjustable 2" rack and pinion focuser on the Celestron Omni XLT 120 accepts both 2" and 1.25" accessories. The telescope includes a 1.25" star diagonal and a 25 mm eyepiece that will provide 40X magnification in a 50-degree field of view. We recommend you obtain a few more eyepieces to provide a choice of magnifications when viewing celestial, or terrestrial objects.

You can find those objects more easily with the included 6x30 optical finderscope. As its name suggests, this monocular-styled finder provides a low power, 6X magnification to easily locate and center objects in your eyepiece.

The included tube rings come with a Vixen-style dovetail, which will allow you to easily mount the Celestron Refractor OTA refractor on a wide variety of mounts. If you have a mount that you’re not sure of, feel free to contact High Point and we will be happy to help.
